>>"A lot of those stopped without tax or insurance are found to have paid cash for the car and registered it to a false address so ANPR is useless."
Surely, ANPR has the potential to identify that a particular car (or at least a particular set of number plates) is in a particular place at a particular time.
If the car doesn't check out as insured/MOT'd, isn't it useful to know it is (or at least has just been) in a particular place, rather than merely knowing that an address is false?
Surely that gives the chance of intercepting it, if cameras are placed in locations amenable to interception?
Even if plates are cloned, surely the more ANPR around, the easier it is for cloning to be positively identified, and again, vehicles potentially intercepted or followed?
If I'm faced with a traffic charge or other penalty for somewhere I haven't been, aren't I in a better position if both I and a cloned vehicle are flagged up at times/places it wouldn't be possible to drive between, or if they've been flagged up at times when I can actually provide alibis?
